Mermaid?Siren!

The vast ocean is the cradle of life, and all life originates here.

About 45 billion years ago, the first ocean was very small, not even as big as a lake today.

At that time, the layer of crust on the surface of the earth was constantly impacted and squeezed by the violent movement of the earth's interior during the cooling and condensation process, so it became wrinkled and uneven, and sometimes it was squeezed, forming earthquakes and volcanic eruptions, and ejecting magma. with heat.At first, this happened frequently, and then it gradually became less and gradually stabilized.

After the crust is cooled and shaped, the earth is like a long-dried apple, with densely wrinkled and uneven surfaces.Mountains, plains, riverbeds, sea basins, all kinds of terrain are available.

For a long period of time, the water vapor and the atmosphere coexisted together in the sky, and the clouds were densely covered.The sky is dark and the sky is dark. As the earth's crust gradually cools, the temperature of the atmosphere also gradually decreases. The water vapor uses dust and volcanic ash as condensation nuclei, and turns into water droplets, which accumulate more and more.Due to the uneven cooling, the air convection is severe, forming thunderstorms and strong winds, torrential rain and turbid currents.The torrential flood, passing through thousands of rivers and ravines, converges into a huge body of water, which is the primitive ocean.

About 36 billion years ago, a very small primitive cell appeared in the primitive ocean. From then on, the earth began the process of life, and gradually various plants and animals appeared.The world begins to become richer.

And now, 71% of the earth's surface area is covered by the blue ocean, and the reserved land is due to the over-exploitation of humans, and there are fewer and fewer places where animals can live.

2012 was the legendary end of the world, but that year was the beginning of a new life for marine life.

When the movement inside the earth became violent again, the crust was impacted and squeezed, and large-scale earthquakes and volcanic eruptions surged, the horrible scene was like history repeating itself.Earth begins its new turf division.

Human beings can no longer remember how they escaped from that catastrophe. They only know that when they were freed from this catastrophe and 93% of the earth's surface area was turned into oceans, only 63 billion people in the world remained. Less than [-] million.

Human beings can only survive on less than one-third of the original land, and a catastrophe almost wiped out the technological crystallization of thousands of years.

But the cessation of earthquakes and volcanic eruptions does not mean the end of the disaster.

People are horrified to find that there are only two relatively large landmass left, one is Antarctica, and the other is the Qinghai-Tibet Plateau, which was originally part of Asia.

The former is covered with ice and snow all year round, and the low temperature of tens of degrees below zero is not suitable for people to live in now without the power of science and technology, while the plateau environment of the latter is also difficult for people to adapt to.

To live where there are only a few islands left?Now, when there are no ships and the route is unknown, no one will take the risk of finding it.

And the sky is still raining dust and volcanic ash, and this kind of rain can kill people just once.

The homes to live in are gone, the environment has become so bad, a large number of animals and plants have died, the polluted water source is no longer safe, there is no food and water, a large number of weak human beings are slowly dying, and the number of surviving human beings has decreased sharply again.

In order to survive, human beings began to drink simply filtered rainwater, risked their lives to dive into the polluted ocean, fought with the surviving marine creatures, and won more living space in eating and being eaten.

The large amount of algae floating in the sea became their main food source.

Year after year, day after day, when the rain becomes clear and clean again, people find that their bodies have changed, their bodies become stronger, and they can stay longer in the water.

And the most amazing change comes from new life.

There was an uproar when the first boy with fins in his ears and gills behind his ears was born.

People were shocked when the first girl with a mermaid was born.

More and more new life forms with fins, gills and fish tails are being born. While people see the hope of survival, they are also dejected.

Life was born in the ocean. Fish appeared in the ocean 4 million years ago. Some of them landed on land. After hundreds of millions of years of evolution, there are now all-encompassing species. Now, they will return to the ocean again.

The age of mankind is finally over...

The new generation is called mermen, and among them there are only mermaids and murlocs. Mermaids with human bodies and tails are murlocs, and those with fins and gills are murlocs, but all mermaids are female, and all murlocs are female. are all men.

What a clear division, like a formula, never made a mistake.

When time passed, the last human being also disappeared in the long river of history, a new civilization appeared, and the mermaids also divided a new territory.

Mermaids live in the shallow sea area close to the land, that is, within the continental shelf.Instead of relying on the meager supplies of the land, they sought the supplies of survival in the sea.

With the multiplication and growth of the new race, Qianhai can no longer satisfy them. The mermaids set their sights on the deep sea, where there are inexhaustible treasures. As long as they defeat it, they will all be theirs. .

But they forget that since they can evolve themselves, how can those marine creatures that survive on their own not evolve?

This is a fault located on the periphery of the shallow sea area of ​​the New World. It is between the continental shelf and the ocean floor. If the continental shelf in the shallow sea area is still part of the land, then the ocean floor outside the continental slope is the real sea floor.

Its name is Continental Slope, but now the sharks prefer to call it the Forbidden Ring.

A few decades ago, this big land was still a continent. The earthquake that year collapsed the continent, forming a cliff that spanned the three places of Inner Mongolia, Sichuan and Yunnan in the past. The incredible posture perfectly surrounded the entire new continent. Inside the cliff was a shallow sea area with a depth of no more than a few hundred meters, while outside the cliff was an underwater world thousands of meters deep.

Since the catastrophe, the pattern of the world has long changed. Human beings have withdrawn from the stage of history, and various large-scale underwater creatures have become the overlords. It is as if the world has regressed back to ancient times. The ancestral phenomenon reappeared, they were ferocious and powerful, completely unmatched by the current sharks.

And the more powerful the creatures are, the bigger they are, which limits their activity area to the deep sea. The shallow sea area where the mermaids live can easily stranded those big guys, so now they can continue to reproduce safely.

It can be said that this forbidden ring not only destroyed the old world, but also provided protection for the mermaids in the new world. No one can tell whether this is good or bad.

But now, at the edge of this forbidden ring, a group of mermaids floated neatly in the water, swaying gently with the waves. Each of them carried a harpoon on their back, looking ready to go.

Their mission is to explore the sea area beyond the forbidden ring and find more seabed resources.

"Set off."
